Abstract
One new quinolinic scandine-type monoterpeniod alkaloid, 3-oxo-scandine (1), as well as seven known ones (2-8), was isolated from the roots of Melodinus henryi. Their structures were elucidated by extensive spectroscopic analysis. All of the compounds were prepared and evaluated for their anti-inflammatory activities by measuring the inhibitory activity of nitric oxide (NO) in vitro in RAW 264.7 mouse peritoneal macrophages. Compounds 6 and 7 showed significant activities with IC50 values of 8.54 and 5.19 μM, respectively.
